This study was designed to detect L. infantum infection in dogs and to evaluate the factors associated with canine visceral
leishmaniasis in the maroon communities of Menino Jesus de Petimandeua and Itaboca in the municipality of Inhangapi, Par?, Brazil. Whole
blood and intact skin samples were collected from 143 dogs, and a questionnaire was applied. L. infantum DNA was detected by polymerase
chain reaction (PCR) using primers RV1 and RV2. Collection sites were georeferenced to obtain a spatial distribution of the residences visited and
infected dogs. L. infantum DNA was detected in 8.4% (12/143) of the skin samples and in 1.4% (2/143) of the blood samples. On the risk map,
three clusters were observed in Itaboca and one was observed in Menino Jesus de Petimandeua. We observed that most of the inhabitants in these
maroon communities live close to forested areas and do not use protection against insect vectors. The presence of canine reservoirs of L. infantum
associated to environment characteristics (preserved forests and deforested areas) and habits of dog owners (living near forested areas and not
using any protection against insects) may favor the transmission of L. infantum in the studied areas. |
